As oceans warm, coral reef fish might prefer to move rather than adapt

Scientists have new evidence that coral-reef fish — who are capable of adapting to warmer temperatures brought about by global climate change — will probably opt instead to relocate to cooler parts of the ocean. In experiments using a fish found in coral reefs around the world, the blue-green damselfish, researchers found that the fish were capable of adapting to living in water 2-4 degrees Celsius above their normal summer temperatures; however, when given the slightest chance, the fish moved to cooler water
